I don't think that 5.5mg red xannies are manufactured by any pharmaceutical company. if you got yours from the black market then we can't tell you at all what is in those pills or if it really is alprazolam the legitimacy of the dosage. The only answer you will probably get will be: send them to a drug testing company, buy some test kits (if they are available for xanax/alprazolam) and find out yourself. Probably this thread will get closed, as we don't identify drugs on bluelight as a matter of HR.
